LXC - (LinuX Container) is an operating system-level virtualization method that allows multiple isolated Linux systems to run as a single host that acts as the controller. Virtualization is not provided through Virtual machines, but rather through a virtual environment with a process set and network space. Each isolated system gets its own directory structure, network devices, IP addresses and process table. It's written in C, Python, Shell and LUA.
